No Backlight: Inverter or LCD Bulb?
I am having issues with the backlight on my macbook. I've done some research and it seems like it is either the inverter (or inverter cable) or the LCD bulb itself.
I have one additional finding that I was hoping is able to distinguish these two problems. When I first started experiencing problems with the backlight, I was able to use the brightness keys on the keyboard to adjust the brightness and get the backlight to start working. When the screen was black, I'd adjust the brightness to the lowest setting and then adjust it up one. In must cases the backlight would come back on, but other times it would flicker and go back out. When it came on, it would stay on as long as I left it dim and I was still able to use the screen normally. However, if I tried to adjust it to the brighter settings, it would flicker and go black again.
I was able to do this for a few months, but now the backlight is out completely. I am wondering if this descriptions sounds more like the bulb going out or a failing inverter?
Is this a good question?
